Now, China desires to transform that on-line reputation into real-life tourism.
First step: promote it to Chinese language home vacationers.

How the surprise was shaped

“If the sulfate in your water is bigger than the calcium, all of the calcium is used up, which leaves you with an extra of sulfate and you’ve got a sulfate lake,” explains Hong Kong Baptist College geography professor Bernie Owen.
Xiechi can be a “closed basin” lake — which means it would not circulation out to a river or ocean — which explains how its salt content material stays so excessive.
“Water is available in with salt, water escapes, salt stays behind, extra water is available in with salt, evaporation. Salt stays behind,” Owen explains. “There is not any outlet on this one. It’ll simply progressively change into saltier and saltier and saltier.”
However what about these attractive colours which have made the lake so well-liked with photographers? They must do with the species of animals and vegetation dwelling within the water.

Purples you (additionally) are inclined to get with inexperienced algae. After which greens or oranges (happen) in very saline lakes.”

Two extra such recognitions would tie China with Italy for the highest spot on the UNESCO listing.
There’s some excellent news for wannabe vacationers who hope to go to Xiechi Lake — it is not but as well-liked or crowded as different vacationer spots in China.
That’s prone to stay unchanged so long as China stays principally closed to worldwide tourism. The nation closed its borders in early 2020 and stays one of many few locations on the earth nonetheless adhering to a “zero Covid” technique that features very strict quarantine insurance policies.
